TO ALLWHOM IT MAY CONCERN:`

Be it known that L'MICHEL VANDER WEID-E, of St. Petorsburgh, Russia, have invented a new and useful Improvement in Submarine Lantern; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication.

This invention relates to a new apparatus for submarine lighting, for the use of divers andother purposes, whereby the diliiculties of submarino exploration are greatly diminished.

And the invention consists in so constructingand arranging the parts ofthe lantern, that gas is generated for supplying the flame, and provision is made for supplying the ilame with ai? und for discharging the products of combustion and condensed air and gases formed in the lantern, and in protecting the tlame and reservoir from water when the lantern is submerged, .as will be hereinafter more fully described.

'Fig'nrel is a vertical section of the lantern through the linea z of iig. 2, showing its construction and manner ol' operation.

Figure@ is abroken or sectional top view of the lantern, showing the air-passage inthe shell, yand the manner in which the glass or transparent sides of the lantern are fastened in the shell and leakage prevented,

, the section being through the line y g/ of fig. l.

Similar letters of refereneeiudieate correspondingparts.

Arepresents the shell, which is alongitudinal section of a hollow cylinder with channels or passages therein, for the entrance of air, and for the discharge 'of incombustible gases or condensed air.

These channels are marked, respectively, B and C. p

Both are connected with flexible tubes,`whieh may be of any desired length, but which must extend above the surface ofthe water-when the lantern is submerged.

D is the tube. through which air is.'introduced, and is connected'with the channel C.

This channel isiopen atsits upper end and closed at its lower end, as'seen in the drawing.'

E is'the tube through which. the condensednir or incombustible gases are discharged.

'.lhis tube is connected with the channel B, which is open at the bottom and closed at the top,4as seen.

The flexible tubes D and E are attached to the rigid tubes F and AG by screw-connections, as seen at 7i L.

I is a funnel in the air-tube D, through which air' may beintroducedby bellows before the lantern is submerced. DJ is a flange on one Side of the shell, to which an annular packing-ring c is attached by any suitable number of screws. Y

The green lines in iig. 2, marked z' z', represent the glass sides of the lantern.

Vm isa. packing-ring on the other side ofthe lantern from theilange J. Y

Beth the rings 7c and m conne rubber or` other elastic packing in contact with the glass, as seen at n n.

O is the reservoir for the liquid. y y Y 'lhc liquid used is of a volatile nature, being composed of alcohol and spirits of turpentine mixedin proper proportions. v .Y

P is the burner, which may contain a capillary, if necessary, to raise the liquidin the burner a certain distance by capillary attraction.

By elevating the temperature of the liquid or burner slightly, by burning alcohol around it, the liquid is vaporiz'ed, and a gas is formed which isqdischarged through. the small' orifices seen near the end of the burner at q. A regular wick-tubmmay bc used, so as to consume any burning-iluid without vaporizing it if foun'd more convenient. I

R. is a tube closel by a cock for the discharge of air, when it may be necessary to discharge it.

S S are rings attached to bars at the base of the lantern, to which cords are attached lfor suspending tho` lantern or lowering and raising it. i

T represents a/knob for` attaching u. ring, by which the driver carries 'or handles the'lantern.

I claim as new, and desire tosecure by Letters Patenti A The submarine lantern having the semicir-cular channels B C, formed concentrically in the body of the Acylinder, the former being closed :tt the top and opening into the cylinder at the bottom, and the latter closed at the bottom and opening into the cylinder :it the top, said 4ohalmbers communicating, respectively, with the supply and exhaust-tubesF Gr upon leztc'n side of the burner, :ts hei-ein described, for the purpose specied.

The above specification of my invention signed by me, this 15th day of April, A. D. 1868.
